Delayed Neurologic Deficit due to Foraminal Stenosis following Osteoporotic Late Collapse of a Lumbar Spine Vertebral Body
Figure 2
The 85-year-old woman with an L3 vertebral body fracture, detected two weeks after the initial onset by magnetic resonance imaging, presented with back pain, bilateral leg pain, and weakness after four months of conservative treatment. The lateral radiograph (a) in supine position showed the collapse of the L3 vertebral body compared with the initial radiographs. Reconstructed computed tomography (CT) taken in the supine position (b) shows an osteoporotic vertebral collapse of L3 (arrowhead) with an interior bony defect. Parasagittal images of the CT scan show the collapsed vertebral body on both sides (c) and (d). Note the fracture lines from the undersurface of the L3 pedicle to the anterior side of the L3 vertebral body (arrowhead).
